[0032] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0033] See Figure 1-5As shown, a slide rail for a car seat includes a mounting seat 1 and expansion plates 2 and a tail seat 3 on both sides and the top thereof. A driving mechanism 4 is fixedly connected to the mounting seat 1, and a driving rod 15 is matched with the bottom of the driving mechanism 4. A support plate 5 is provided at the bottom of the mounting seat 1, a connecting head 6 is fixedly connected to the support plate 5, and a connecting plate 7 is fixedly connected to the bottom of the connecting head 6. A guide rail 8 is fixedly connected to the bottom of the expansion plate 2, and a slide seat 9 is movably sleeved on the guide rail 8. The top of the connecting head 6 is fixedly connected to an auxiliary rail 10. The surface of the mounting seat 1 is fixedly connected to a limiting seat 11 and a support seat 12, and the driving rod 15 simultaneously moves through the support seat 12. A lubrication portion 13 is provided at the inner end of the slide seat 9, and an elastic layer 14 is fixedly connected to the inner side of the top of the connecting plate 7. The top of the elastic layer 14 is also fixedly connected to the bottom of the expansion plate 2.

[0034] In an embodiment of the present invention, the limiting seat 11 is convex and protrudes from the surface of the mounting seat 1, while the supporting seat 12 is T-shaped and is co-located on the outside of the limiting seat 11. The limiting seat 11 is used to limit the auxiliary rail 10, and the supporting seat 12 is used to limit the driving rod 15.

[0035] When the driving rod 15 is telescopically moved under the control of the driving mechanism 4, the support seat 12 can effectively ensure its activity stability. At the same time, the movement of the driving rod 15 drives the auxiliary track 10 to move and adjust along the limit seat 11, and the limit seat 11 can effectively ensure its activity stability.

[0036] The support plate 5 is set as a rectangular plate and is fixedly connected to the outer side of the connecting head 6. The connecting head 6 is set in a rectangular shape, and its top outer side is fixedly connected to the driving rod 15, and the top inner side is fixedly connected to the auxiliary track 10. The driving rod 15 and the auxiliary track 10 are both set vertically, and the driving rod 15 is located on the outside of the front of the auxiliary track 10. The connecting plate 7 is set horizontally in an "L" shape as a whole, and its front side is set to be angled and upwardly protruding, with mounting screw holes distributed on the surface. At the same time, the connecting plate 7 and the connecting head 6 are fixedly plugged in, and the effect of connecting and fixing to the back of the external seat is achieved through the connecting head 6 and the connecting plate 7, and the effect of driving the connecting head 6 to be raised and lowered as a whole is achieved through the driving rod 15, and the effect of ensuring the adjustment stability of the driving rod 15 is achieved through the auxiliary track 10.

[0037] After connecting the connecting plate 7 and the back of the external seat, the driving rod 15 is raised and lowered under the control of the driving mechanism 4, driving the external seat to complete the adjustment operation. During the adjustment process, the auxiliary track 10 simultaneously slides along the limit seat 11, thereby ensuring the adjustment stability of the external seat by the driving mechanism 4 and the driving rod 15.

[0038] Two groups of guide rails 8 are provided, which are located on both sides of the bottom of the mounting seat 1. The slide 9 is rectangular, and its two ends are trapezoidally buckled with the two sides of the guide rail 8. The interior of the two ends of the slide 9 is hollow, and a lubrication addition port is provided on the surface. The contact surface of the lubrication part 13 and the guide rail 8 is provided with two groups of lubrication ports. A mounting screw hole is provided on the top of the slide 9, and the slide 9 is connected to the bottom of the external seat. At the same time, the guide rail 8 and the slide 9 that are buckled in a trapezoidal manner cooperate with the lubrication part 13 with a lubrication port to ensure the sliding stability and sensitivity of the two, thereby avoiding jamming under stress.

[0039] The installation of the external seat can be completed by connecting and installing the slide 9 and the bottom position of the external seat. During the adjustment process, the slide 9 slides along the guide rail 8. The user can add lubricating oil to the slide 9 in advance so that the lubrication part 13 can ensure stability and sensitivity between it and the guide rail 8.

[0040] The elastic layer 14 is set as a plastic corrugated layer and is located between the guide rail 8 and the support plate 5. The elastic layer 14 is used to cover and protect the top of the guide rail 8. When the external seat is adjusted, as the external seat slides, the connecting plate 7 drives the elastic layer 14 to adaptively stretch and compress, thereby covering and protecting the exposed position on the top of the guide rail 8.
